Description

Technical Field

[0001] The present invention relates to the technical field of protective covers, in particular to an enhanced self-locking switch machine protective cover. Background Art

[0002] A switch is a crucial signaling device used to reliably change turnout positions, alter turnout opening directions, lock turnout points, and indicate turnout position. It effectively ensures driving safety, improves transportation efficiency, and reduces operator workload. Due to the continuous upgrade of switch machines, existing protective covers are no longer suitable for newer ones. Removing these protective covers is time-consuming and labor-intensive, making maintenance inconvenient and inefficient. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the removal of the existing protective cover is time-consuming and labor-intensive, resulting in inconvenient maintenance and low maintenance efficiency, an enhanced self-locking switch machine protective cover is provided.

[0004] The present invention solves the technical problem by employing a technical solution: an enhanced self-locking switch machine protective cover, comprising a protective cover body, a locking mechanism disposed on the protective cover body, and a locking pin used in conjunction therewith and disposed on the switch machine. The protective cover body is further provided with a control mechanism for controlling the displacement of the locking mechanism and locking or unlocking the locking mechanism and the locking pin, thereby locking or unlocking the protective cover body on the switch machine. Compared to the prior art, the present solution utilizes a control mechanism to control the displacement of the locking mechanism, thereby controlling the locking or unlocking of the locking mechanism and the locking pin, thereby controlling the removal of the entire protective cover body from the switch machine housing. This facilitates and speeds disassembly, improving maintenance efficiency.

[0005] In order to realize the control mechanism, the control mechanism further includes a connecting rope, one end of which is arranged on the lock body mechanism. By connecting one end of the connecting rope to the lock body mechanism, the lock body mechanism can be moved by controlling the displacement of the connecting rope, which is convenient for the staff to control.

[0006] In order to facilitate the control of the connecting rope, the control mechanism further includes a displacement mechanism for driving the connecting rope to move. By arranging the connecting rope on the displacement mechanism, the displacement mechanism can drive the connecting rope to move, thereby driving the lock body mechanism to move.

[0007] In order to facilitate the implementation of the displacement mechanism, the displacement mechanism is further provided on a displacement plate on the protective cover body, and the other end of the connecting rope is provided on the displacement plate. By providing the other end of the connecting rope on the displacement plate, the displacement of the displacement plate drives the displacement of the connecting rope, which facilitates control by the staff.

[0008] To facilitate installation and subsequent maintenance, one end of the displacement plate is hinged to the protective cover body, and the other end of the connecting rope is provided with a limit block. The displacement plate is provided with a limit slot that matches the limit block. The displacement plate is provided with a clamping slot that matches the connecting rope. The clamping slot extends inward from one side of the displacement plate to the limit slot, and the limit slot and the clamping slot are interconnected. By clamping the connecting rope in the clamping slot, the clamping slot can limit the connecting rope, and the limit slot limits the limit block, making installation and subsequent maintenance easier for staff.

[0009] To prevent the connecting cord from getting tangled and stuck, the protective cover body is further provided with a protective tube, which is arranged between the control mechanism and the lock mechanism, and the connecting cord is passed through the protective tube. Passing the connecting cord through the protective cover serves as a guide for the connecting cord, effectively preventing the connecting cord from getting tangled or stuck.

[0010] Since the rods of the switch machine require frequent maintenance, while it is convenient to remove the entire protective cover from the casing, the protective cover body is relatively heavy. To facilitate maintenance of the rods on the casing, the protective cover body further includes a casing cover and a rod cover detachably mounted on the casing cover. The casing cover is used to cover the casing of the switch machine, and the rod cover is used to cover the rods of the switch machine. The protective cover body is composed of a detachably connected casing cover and rod cover. When maintaining the rods, only the rod cover can be removed, and the rods can still be maintained, thereby reducing the labor intensity of the staff.

[0011] To achieve detachable housing cover and rod cover, the housing cover is further provided with a mounting hole, and the rod cover is provided with a mounting block that matches the mounting hole. The mounting block is tightened within the mounting hole by a tightening block. The mounting block is placed within the mounting hole and tightened by the tightening block, thereby achieving detachable mounting of the rod cover on the housing cover.

[0012] To ensure that the housing cover is stably and reliably tightened on the rod cover, the mounting hole is further provided with a first tooth groove on the contact surface of the mounting block, and the mounting block is provided with a first latching tooth that matches the first tooth groove, and the first latching tooth is disposed in the first tooth groove. The first tooth groove and the first latching tooth cooperate to ensure that the two sets of latching connections are stable and reliable.

[0013] Furthermore, the mounting block is provided with a notch for receiving the tensioning block. The inner circumferential wall of the notch is provided with a second tooth groove. The tensioning block is provided with a second latching tooth that matches the second tooth groove. When the tensioning block is positioned in the notch, the second latching tooth is disposed in the second tooth groove. The second latching tooth and the second tooth groove cooperate to ensure that the tensioning block is stably and reliably tightened in the notch.

[0014] In order to realize the lock body mechanism, further, the lock body mechanism includes an outer shell having a cavity inside, and a through hole communicating with the cavity is opened on the outer shell;

[0015] A slide seat is disposed in the cavity, and a slideway matching the locking pin is provided on the slide seat, the slideway being opposite to the through hole;

[0016] A fixed block is used to cooperate with the external locking pin. The fixed block is arranged on the slide seat along the radial direction of the slide. A limiting section cooperating with the fixed block is provided in the outer shell. The limiting section is an inclined surface arranged to gradually tilt downward from the inside to the outside along the axial direction of the slide.

[0017] And a pre-tightening mechanism, which is arranged in the cavity, is used to control the fixed block to always contact the limit section, and to enable the fixed block to lock the locking pin inserted into the slide through the through hole on the outer shell. When in use, the control mechanism is used to control the displacement of the slide in the outer shell, so that the fixed block is separated from the limit section and the outer shell and the locking pin are unlocked.

[0018] Furthermore, the material of the protective cover body is polycarbonate. The protective cover body is environmentally friendly and recyclable, and is lightweight and easy to install and maintain.

[0019] The beneficial effects of the present invention are as follows: when the enhanced self-locking switch machine protective cover of the present invention is in use, the control mechanism controls the displacement of the lock body mechanism, thereby controlling the locking or unlocking of the lock body mechanism and the locking pin, thereby realizing the control of the entire protective cover body being disassembled from the casing of the switch machine. The disassembly is convenient and fast, which improves the maintenance efficiency and avoids the problem that the existing protective cover is no longer suitable for the new switch machine due to the continuous upgrading of the switch machine, and the disassembly of the existing protective cover is time-consuming and labor-intensive, resulting in inconvenient maintenance and low maintenance efficiency.

[0052] One end of the displacement plate 402 is hinged on the protective cover body 1, and the other end of the connecting rope 401 is provided with a limiting block 403. The displacement plate 402 is provided with a limiting groove 404 that matches the limiting block 403. The displacement plate 402 is provided with a card slot 406 that matches the connecting rope 401. The card slot 406 extends inward from one side of the displacement plate 402 to the limiting groove 404, and the limiting groove 404 and the card slot 406 are connected to each other.

[0053] The protective cover body 1 is further provided with a protective tube 405 , which is provided between the control mechanism 4 and the lock mechanism 2 , and the connecting rope 401 is passed through the protective tube 405 .

[0054] The protective cover body 1 includes a housing cover 101 and a rod cover 102 detachably mounted on the housing cover 101 . The housing cover 101 is used to cover the housing 501 of the switch machine 5 , and the rod cover 102 is used to cover the rod 502 of the switch machine 5 .

[0055] The housing cover 101 is provided with a mounting hole 103 , and the rod cover 102 is provided with a mounting block 104 matching the mounting hole 103 . The mounting block 104 is tightened in the mounting hole 103 by a tightening block 110 .

[0056] The mounting hole 103 is provided with a first tooth groove 106 on the contact surface of the mounting block 104 . The mounting block 104 is provided with a first latching tooth 105 matching the first tooth groove 106 . The first latching tooth 105 is disposed in the first tooth groove 106 .

[0057] The mounting block 104 is provided with a slot 107 for placing the tensioning block 110, and the inner peripheral wall of the slot 107 is provided with a second tooth groove 108.

[0058] The lock mechanism 2 includes an outer shell with a cavity inside, the outer shell is clamped on the housing cover 101, and has a through hole communicating with the cavity;

[0059] A slide seat is arranged in the cavity, and a slideway matching the locking pin 3 is provided on the slide seat, and the slideway is opposite to the through hole;

[0060] A fixed block is used to cooperate with the external locking pin 3. The fixed block is arranged on the slide seat along the radial direction of the slide. A limiting section cooperating with the fixed block is provided in the outer shell. The limiting section is an inclined surface gradually inclined downward from the inside to the outside along the axial direction of the slide.

[0061] And a pre-tightening mechanism, which is arranged in the cavity, is used to control the fixed block to always contact the limit section, and realize that the fixed block will lock the locking pin 3 inserted into the slide through the through hole on the outer shell. When in use, the connecting rope 401 of the control mechanism 4 is fixed to the slide. The control mechanism 4 is used to control the displacement of the slide in the outer shell, so that the fixed block is disengaged from the limit section and the outer shell and the locking pin 3 are unlocked.

At this time, the locking pin 3 and the lock body structure can be separated, that is, the protective cover body 1 is removed from the casing 501 of the switch machine 5. At the same time, when only the rod cover 102 on the casing cover 101 needs to be removed, the tightening block 110 is pulled out from the slot 107, and the mounting block 104 is removed from the mounting slot, thereby completing the removal of the rod cover 102 from the casing cover 101.

[0063] Example 2

[0064] Example 2 is an application of Example 1, specifically: Figure 17As shown, a switch machine 5 is characterized by including a housing 501 on which the aforementioned enhanced self-locking switch machine protective cover is mounted. The locking pin 3 is fixed to the housing 501 of the switch machine 5. The displacement plate 402 is then controlled to move the slide, aligning it with the locking pin 3 and inserting it into the slideway. The displacement plate 402 is then released, and the spring in the pre-tightening mechanism within the lock mechanism 2 drives the slide back to its initial position, completing the fixation between the lock mechanism 2 and the locking pin 3. This also allows the protective cover body 1 to be mounted on the housing 501.

[0065] The above description of the preferred embodiments of the present invention is intended to serve as a guide. Based on the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
